STOP-MOTION FOR LOOMS.

Specification of Letters Patent.

Application filed July 1. 1920. Serial No. 393,237.

To all whomt't may concern:

Be it known that I, SOLQZ-JON KAirnLoAR, a citizen of the Republic ofPoland, residing at Paterson, in the county of Passaic and State of NewJersey, have invented certain new and useful Improvements in Stop-Motions for Looms, of which the following is a specification. I

This invention relates to means for stopping a loom of the box-loom typewhenever it inadvertently happens that when a shuttle is in position tobe shot across the lay or batten another shuttle is in a box which isalined with the lay, so that a smash. would occur if the first shuttlewere thrown. The

object of the invention is to provide a means of this lrind which, whileefficient and reliable in operation, shall be simple in construction.

in the accompanying drawing,

Figure l is a front elevation of the batten structure and the parts ofmy mechanism which are carried thereby;

Fig. 2 is a plan view showing the batten structure, thebreast-beam-including part of the loom frame, and my mechanism;

Figs. 3 and 4e are sectional views on the line 3-3, Fig. 2, showing theparts in the positions they occupy before and after the knocking-01faction has occurred; and

Fig. 5 is a sectional view on the line 5-5,

Fig. 1.

On the loom-frame a. is the breast-beam Z2, and suitably arranged toreciprocate toward and from the breast-beam is the batten c. d indicatesasingle shuttle box at one end of the batten and e a vertical series ofshuttle boxes moved up and down at the other end of the batten by anysuitable means, not shown. Each shuttle box has a binder c which ismovable outwardly by the shuttle, in the usual way, when the same entersthe box, such binder being in the present instance a part of my meansfor stopping the loom and so preventing a smash.

In the frame a underthe breast-beam is journaled the usual knock-offshaftf, the same being provided in the present instance with a collar 9having a downwardly projecting toe h.

A plate 2' is secured to the front of the batten opposite the collar 9and is formed with a vertical dovetailed groove j. This plate has aforwardly rojecting hookshaped arm is in which 1S, fulcrumed the daggerZ arranged when the batten moves forward to miss said toe or impingeagainst the same, according as the dagger stands do pressed or elevated.In the groove 7' slides a block m which is normally impelled downwardlyby gravity (assisted by a spring a, if desired). This block m has adepending stem m which is pivotally connected to the rear end of thedagger. The block has a cross cut or horizontal groove o'in its frontface.

The block is normally held elevated, thus holding the free end of thedagger depressed, so as to miss the toe 7b of the collar g, by theprotector rods 39 alined with each other and journaled horizontally inbrackets Q attached to the batten. The inner end of each rod is bent toform a crank 1' which is engaged in the groove 0 and is normally heldtherein by a spring t which is coiled about the rod and is secured atone end to a collar u, adustably secured on the rod, and at the otherend to the adjoining bracket 9. The outer end of the protector rod whichadjoins the series of shuttle boxes 6 has an arm 4) which bears againstthe shuttle binders e of those boxes; the outer end of the otherprotector rod is formed as a crank w and bears upon the forwardlyprojecting arm of a lever to, fulcrumed in the batten and having anupwardly projecting arm to bear against the binder e for the adjoiningor single shuttle box (Z.

The operation is as follows: So long there is only one shuttle in thebox (Z and one of the boxes 6 alined with the batten the means toactuate the knock-off shaft (such means including the slide m) will beheld in the position shown in Fig. 1 or Fig. 3, 'i. 6., so that thepoint of the dagger will be depressed and consequently miss the too it,this is because, although the shuttle present has caused thecorresponding protector rod to rock to the position shown in Fig. 4c,since there is no shuttle in the box alined with and at the other end ofthe batten, the other protector rod remains in looking engagement withthe groove 0 of the slide, holding it elevated. But if both boxes alinedwith the batten contain shuttles, then both protector rods will havebeen rocked and so caused to release the slide, so that it falls andallows the dagger to assume the position shown in Fig. 4, and then onthe next beating-up movement of the batten the dagger will Patented Nov.9, 1920.-

strike the toe h and so rock the knock-off shaft. V

The daggerdmpact face of toek is preferably arranged at such an anglethat on the dagger impinging thereagainst and rocking the knock-offshaft to the dotted line position, said face Will assume an inclinedposition (dotted lines, Fig. 4) and so serve as a cam thereupon todepress the point of the dagger and cause the latter to elevate theslide, so that upon removal of one of the two shuttles the correspondingprotector rodavill again interlock with the slide and hold it and thedagger in the idle position. I

Having thus fully described my invention,

7 What I claim as neWand desire to secure by Letters Patent is p I 1. Incombination, With the loom fraiiie, knock-off means movable therein, andten structure movable in said frame and having shuttle-boxes at the endsthereof, means to actuate the knock-off means including a slide andmovable in the batten structure from a position to clear to a positionto en'- 25 gage the knock-off means and normally impelled to the latterposition, and separate means, disconnectively coupled with the slide, tohold the second means in the former position, each of said separatemeans being respectively actuable by a boxed shuttle to release theslide. i

2. 111 combinatiOm-with the looni firame, knockofi' means movabletherein, and a batten structure movable in said frame and havingshuttle-boxes at the ends thereof, means to actuate the knock-oil meansincluding a slide movable vertically in the batten structure from aposition 'to clear to a position to engage the knock-"0E means andnormally impelled to the'latter position, and separate means tohold'th'e second ineansin the former position, each of said separatemeans includ ing a protector rod journaled in tliebatten and 'actuahleby one of two boxed shuttles alined with the batten and having a crankmovable into and out of interlocking err gagement with the slide.

In testimony whereof I aflix mysignature.
